This is a general account of the history and architecture of Crusader castles in the Kingdom of Jerusalem, County of Tripoli and Principality of Antioch between 1099 and 1291, the years during which the Crusaders had a permanent presence on the Levantine coast.

Has studies Arabic at the Middle East Centre for Arabic Studies. Went on to read Arabic, Persian & History at Cambridge. Taught in the Department of Medieval History at St Andrews since 1972, and was elected Fellow of the Royal Society of Edinburgh (2000).
A very solidly put together piece of research, though hardly a book to be consumed by people who are not medieval castle freaks. Very interesting at building historical context.
